Match the layers of the atmosphere with the description that best matches it according to the graph titled temperature profile.

troposphere a) layer closest to the earth where all weather occurs
mesosphere b) temperature increases as elevation increases
mesopause c) temperature remains constant as elevation increases
stratosphere d) temperature remains at a constant zero degrees celius as elevation increases
stratopause e) begins between 50-60km and decreases in temperature as elevation increases

Atmosphere can be broadly divided into four distinct layers based on their altitude and temperature.

These layers are- Troposphere, Stratosphere, Mesosphere, and Thermosphere.

1) Troposphere ( extends upto 18 km from earth surface)- a layer that is closest to the surface of earth. It is called zone of weather as all the weather phenomenon ( such as storm, wind, precipitation, formation of clouds) occur in this layer. Temperature decreases with altitude in this layer.

2) Stratosphere (extends from 18 km to 50 km) - a layer above troposphere, where temperature increases with increase in altitude.

A boundary between stratosphere and mesosphere where temperature remains constant as elevation increases  is called Stratopause.

3) Mesosphere (extends 50 km upto 85 km) - a layer above stratosphere, where temperature decreases with increase in altitude.

A boundary between mesosphere and thermosphere, where temperature remains constant as elevation increases  is called Mesopause.

4) Thermosphere (extends from 85 km upto 600 km)-  a layer above mesosphere, where temperature again increases with increase in altitude. It is an extremely hot layer because of absorption of X rays and UV rays.

Thus, correct match for the question is-  

Troposphere -A) Layer closest to the Earth where all weather occurs.

Mesosphere- E) begins between 50-60km and decreases in temperature as elevation increases.

Mesopause- C) temperature remains constant as elevation increases.

Stratosphere -B) temperature increases as elevation increases.

Stratopause -D) temperature remains at a constant zero degrees Celsius as elevation increases.
